Garment for bioinformation measurement having electrode, bioinformation measurement system and bioinformation measurement device, and device control method

Abstract

The present invention provides a garment for measuring biological information, a biological information measurement system, a biological information measurement device and a method of controlling thereof capable of measuring biological information with accuracy regardless of variations of the constitution of each examinee. When an examinee wears a biological information measurement shirt 301 , four limb electrodes 351 and 352 are arranged at positions so that the electrodes cover the body surface other than around the clavicle of the examinee. At that time, four limb electrodes 362 and 363 are assigned to positions so that they cover about the pelvis of the examinee. Also, during the use of the shirt, chest electrodes 353˜358 cover from the body surface (around lower part of left side of the body) of a presternal region around the left thorax of an examinee for a perpendicular direction of the body axis (a direction perpendicular to the length of the shirt) and the electrodes are assigned so as to cover from the body surface around the fourth rib to that around the sixth rib.

What is claimed is: 
     
       1. A garment to measure biological information, the garment formed of a nonconductive material having elasticity so as to fit on an upper body of an examinee,
 the garment comprising chest electrodes, formed of a conductive material, to acquire a heart potential from a chest part under a condition of less myoelectric influence, regardless of individual differences in heart position, the chest electrodes located in the garment to cover from a body surface around a fourth rib to a body surface around a sixth rib, and capable of delivering the potential to a cardiogram analysis device, the chest electrodes being arranged along a body axis of the examinee in parallel lines in at least six positions located from a near presternal region of the garment to approximately a left chest lateral part of the garment. 
 
     
     
       2. A garment to measure biological information, the garment formed of a nonconductive material having elasticity,
 the garment comprising chest electrodes, formed of a conductive material to acquire a heart potential from a chest part when an examinee wears the garment, each of the chest electrodes having a length of more than 5 cm and less than 30 cm along an axis, the chest electrodes being arranged adjacently on the chest part along a body axis of the examinee in parallel lines from approximately a front center of the garment to approximately a left side of the garment to cover the chest part around ribs on an anterior surface of a heart. 
 
     
     
       3. A garment to measure biological information, the garment formed of a nonconductive material,
 the garment comprising chest electrodes, formed of a conductive material, to acquire a heart potential from a chest part under a condition of less myoelectric influence, regardless of individual differences in heart position, the chest electrodes placed in the garment to cover a body surface on a chest part and capable of delivering the potential to a cardiogram analysis device, the chest electrodes being arranged on the garment between a near presternal region and approximately a left chest lateral part area, each of the chest electrodes arranged in parallel along a body axis of an examinee to cover the body surface around ribs on an anterior surface of a heart. 
 
     
     
       4. The garment according to  claim 1 , wherein the garment is a shirt worn on an upper body of the examinee, the shirt further comprising four limb electrodes having dimensions so as to at least cover one of a body surface of near a collar bone of the examinee and a body surface near a pelvis of the examinee and capable of acquiring an electric potential and capable of delivering the potential to the cardiogram analysis device. 
     
     
       5. The biological information measuring garment according to  claim 1 , wherein the garment further comprises at least one chest electrode at a position from around the presternal region to a position near a side of a right chest or a position from near a side of a left chest to a position near a back, in addition to the chest electrodes. 
     
     
       6. A biological information measurement system comprising the garment according to  claim 1 , and a cardiogram analysis device, wherein the cardiogram analysis device comprises:
 electric potential information acquisition means for acquiring information on electric potentials based on electric potentials delivered from a plurality of chest electrodes; 
 electric potential comparison means for comparing amplitudes of the acquired electric potential information; 
 electric potential selection means for selecting the chest electrodes detecting a larger amplitude as electric potential information to be based on an output of cardiogram in accordance with the comparison result of the electric potential comparison means; and 
 cardiogram analysis output means for outputting cardiogram data after analysis of the electric potential information detected by the selected chest electrodes.
